No Captcha ReCaptcha 0.1.6b breaks registration of V 2.2

I just testet "No Captcha ReCaptcha" under a recent version of V 2.2 and it seems to break the registration page. It blank the whole page and removes the master template it seems. Only the registration forms appeas stripped of the HEAD and every other code in the HTML.

Someone can help me me what might have changed from 2.1 to 2.2 so that the plugin is able to corrupt the rendering?
